I am closing in on the end of my 90 days of a status match from AS Gold to DL Gold (I'm going to be ~ 200 miles short with a week to go, but expect a trip before the cutoff).

So, assuming I make the match and get Gold, what do I have to do to reach Platinum from there?

Some details: I will have around 25k of flown miles on DL (with my DL FF#) this year on Oct 18 when the challenge ends.
In the last year, I have flown around 95k on Delta metal, (with all my points going to AS before the challenge).
I expect to take one or two trips to Asia by the end of the year
I split my time between SEA and MEM

I'm considering getting a Delta Amex-will MQMs help here?

So, how do I get to Platinum?

Thx
